I just bought a house with a profile 20 and am trying to get it to work. i prime the auger and it feeds fine, i get a flame going, then it stops feeding. if i turn the stove off/on it will begin to feed again, then stop again-turn off/on, it feeds, then stops. i am very new to pellet stoves so any suggestions would help. i plan on giving it the complete cleaning after work today.
